SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 270,104, dated January 2, 1883.

Application filed August 18, 1882. (No model.)

' To all whom it may concern.-

Be it known that I, GEORGE MILLER PALM- ER, of the village of Plattsbnrg, in the county of Clinton and State of New 'York, have invented a certain new and useful Improvement in Sewing-lilachines; and I do hereby declare that the following is a full, clear, and exact description of the same. I

p This invention relates to an improvement in the mechanism for operating the take-up lever of a sewii1g-machine,and has for its object to dle-bar moves vertically imparts motion to said take-up lever.

My invention consists in doing away with one of the rivets for attaching the cross-head to'thcneedle-bar and substituting therefor a stud which will serve the double purpose of attaching the heart-motion cross-head and driving the take-up lever.

For more complete comprehension of my improvement reference must be had to the accompanying drawings, where similar letters of reference indicate like parts, and where Figure l is a view of the inside of a faceplate showing the general arrangement of parts according to my invention; Fig. 2, a sectional side elevation of the same, and Fig.

I 3 a perspective view of cross-head and part of needle-bar with stud in position.

A represents the face-plate, of any of the usual or desired constructions, B the take-up lever, preferably of the shape shown--viz., a regular continuous curve-but not necessarily confined to this shape. V

O is the needle-bar, hearing as usual on the face-plate A, and having attached to .it the heart-motion cross-head I) by means of a rivet, d, at one side of its cam-groove D, and at the other by a stud, E, which passes through said cross-head and needle-bar, so that its end projects inwardly and bears against the edge of the take-up lever B. Motion is imparted through the heart-shaped cam-groove D and a roller in the usual way to the needle-bar, and as it slides up and down draws the stud E along the edge of the take-up lever and throws same back and forth in the same manner as at present, as will be readily understood.

Itwill be seen that by doing away with the old driving-stud, and making the stud E serve the double purpose of driving-stud and rivet, I save drilling an extra hole in the needle-bar, and, besides, it enables me to use a regular continuously-curved take-u p lever with greater facility than could be done with the pnesent device.

What I claim, and desire to secure by Letters Patent, is as follows:

In a sewing-machine, the combination, with the heart-motion cross-head, the needle-bar and take-up lever, of a stud passing through said cross-head and needle'bar, and serving also to actuate the take-up lever, substantially as set forth.
